IoT chip production line 200mm is good to build a 200mm production line based on domestic equipment is very important

With the rapid development of the Internet of Things, the 200mm production line has been the main product actively developed by various chip manufacturers. The 200mm production line was produced at the end of the last century. According to the average life of the original production line, it only has a life span of 15 years. Now it has been used for nearly 20 years. Many of them have reached the stage of scrapping. Many used equipment cannot be purchased. The 200mm equipment is spare parts. Less source, resulting in maintenance difficulties. This may lead to a sharp rise in the price of used equipment, which will make the 200mm production line lose its attractiveness.

With the development of the Internet of Things, 200mm (8-inch) wafer production lines have been welcomed, and capacity utilization has increased significantly. Therefore, it is recommended that China should establish a 200mm production line based on domestic semiconductor equipment as soon as possible. This is based on a high degree of national strategy. Recently, the possibility that the United States has provoked trade friction against China has risen, so we should prepare for the most unfavorable situation.

The 200mm production line in the Internet of Things era is a hot spot

The global 200mm production line is in a special historical period. Mobile technology has promoted the development of bio-networking, 5G, cloud computing, AI and other technologies, and has promoted the expansion of the global Internet of Things market. More than 10 billion intelligent terminals will access the network, bringing unprecedented opportunities to chip manufacturers, especially the Internet of Things. The chip uses a large 200mm production line for wafer fabrication, which brings opportunities to 200mm manufacturers.

According to ICInsight's forecast for the IoT market in September 2016, the market size in 2015 was 15.4 billion US dollars, up 29%; in 2016, it was 18.4 billion US dollars, up 19%; in 2017, it was forecast to be 21.1 billion US dollars, up 15%; 2019 The forecast is $29.6 billion, an increase of 17%. So why is the IoT chip favoring the 200mm production line?

First of all, the R&D investment of advanced process technology is too high, and it is difficult to get the favor of a large number of customers. Usually, the design cost of a product (such as 28nm) needs to be invested 7 million US dollars, and the future sales of its products must be at least 10 times, that is, 70 million US dollars, in order to achieve financial balance.

If the design cost of the product is 357 million US dollars (such as 10 nm), then the sales of the product should reach 3.57 billion US dollars to achieve financial balance. Obviously it is very difficult to find such a large-scale application market. This has led to fewer and fewer customers using advanced process processes.

Second, the future Internet of Things market is in a pyramidal form. According to the GSMA, by 2020, the global connected equipment will exceed 27 billion units, and mobile internet equipment is expected to reach 10.5 billion units. The new market opportunities will further increase, mainly focusing on M2M (machine-to-machine, that is, all enhanced machine equipment communication and The general term for network capability technology and the field of consumer electronics.

Although the Internet of Things is siliconizaTIon of everything (everything can be "silicided" and contains semiconductors), compared with the previous markets, it has a large variety of demand, but the amount is not large, almost no more than 1 billion In the case of volume, even 100 million units in a single market segment are rare. IBS estimates that only a few IoT products will sell more than 10 million units by 2020.

Finally, IoT devices primarily use analog and mixed-signal signals and do not require state-of-the-art process. The main product types include sensors, power supplies, human-machine interfaces or RF. Their functions do not require shrinking processes such as advanced processes, and do not require low thresholds and microcurrents. Accordingly, the most widely adopted design in 2015 was 130 nm, and in fact 180 nm was also used quite well. In the next few years, 65nm, 40nm and 28nm processes may be used.

200mm production line needs to pay attention to maintenance costs

At this stage, the global 200mm production line is not overly described by fiery heat, but it also exposes many problems. Since most of the 200mm production lines were built at the end of the last century, they have been used for nearly 20 years. According to the average life expectancy of the production line of about 15 years, many of them have reached the stage of scrapping. Many used equipment cannot be purchased. The 200mm equipment has fewer sources of spare parts. , resulting in maintenance difficulties. This may lead to a sharp rise in the price of used equipment, which will make the 200mm production line lose its attractiveness.

According to ICInsight, at the end of 2016, there were 5.2 million pieces of 8-inch wafers per month and 5.3 million pieces of 12-inch (300mm) wafers. According to SEMI data, there were 199 8-inch production lines in the world in 2007 and only 178 in 2015. It is predicted to increase to 191 in 2020, which is equivalent to the 2008 level. SEMI believes that China's 200mm capacity will increase by 34% between 2017 and 2021.

In 2015, the global production capacity of 200mm is 11% for simulation, 14% for discrete devices, 47% for OEM, 21% for logic + MPU, 3% for memory and 4% for MEMS and others.

Construction of a 200mm production line based on domestic equipment

The application of the 200mm production line in the Internet of Things is a rare opportunity. The Chinese semiconductor industry should use the power of the industrial chain to seize it. China's semiconductor equipment factory has enough capacity to make 200mm equipment, and has already produced many types of products. The biggest problem at present is that 200mm equipment lacks stable data in the production line and a complete maintenance and service system. In fact, such a process is indispensable for semiconductor equipment companies.

Liu Ming, an academician of the Chinese Academy of Sciences, called for an opportunity to give trial and error of domestic semiconductor equipment. Imported semiconductor devices, which have been modified many times before the product leaves the factory, so the usability of the products is better, and the domestic equipment has few opportunities for actual testing, how can it become a credible excellent product immediately.

Therefore, it is recommended to use the national funds as the mainstay to build a 200mm production line with the best domestically produced equipment and mass production of mature processes. One of the main purposes is to comprehensively examine the actual performance of domestically produced equipment in large production and accumulate domestically produced equipment. The data is constantly being refined.

Domestic equipment factories must go all out to bring their products to the market. The monthly production capacity of the production line can start from 10,000 pieces and gradually expand to 50,000 to 60,000 pieces. It is recommended to choose a 200mm chip manufacturer with full confidence in domestic equipment. From the industrial point of view, there must be corresponding incentive measures.
